Application filed September 30,1922. Serial No. 591,588.

vide novel means whereby light material such as bran may becarried by ablast of air and be-deposited intermittently on the letters or designsof advertising matter.

In the accompanying draw1ngs:

Figure 1 shows in elevation a device constructed in accordance with theinvention, a portion of the cabinetbeing broken away; Figure 2 is a rearelevation, the back of the cabinet being swung to an open position;Figure 3 is a section on the line 3-3 of Figure 2; Figure 4 is a sectionon the line 4-4 of Figure 3.

In carrying out the invention there is provided a cabinet or framelwhichmay be con structed in any desired way. If preferred, the cabinet mayinclude a front .2, sides 3, a bottom 4 and a top 5, the top 5 beinghinged at 6 to the front 2 for vertical swinging movement. The back ofthe cabinet is designated by the numeral 7 and is hinged at 8 to one ofthe sides 3 for horizontal A platform 11 extends across the cabinet fromthe front of the cabinet to the back thereof, and between the sides ofthe cabinet. A partition 18 extends upwardly from the platform 11 to thetop 5 in parallel relation to the front 2. The front 2 of the cabinet 1may be supplied with an upper transparent pane 9 and with a lowertransparent pane 10. A hopper 12 is located between the front 2 of thecabinet and the partition '18, above the platform 11. The upper portionof the hopper 12 may be porous, whereas the lower intake end 13 of thehopper is imperfora-te, so that air cannot escape through the lowerportion 13 of the hopper. The hopper 12 has an opening 14 alined withthe pane 9 in the front 2. Vertical guides 15 are mounted on the sides 3of the cabinet 1 and into the guides 15 a stencil 16 may be inserteddownwardly,

when the top 5 is opened on its hinges 6,

the stencil 16 being perforated in any desired manner, as indicated at17, to form any sort of an advertising design. The

partition 18 has an opening 19 alined with the perforations 17 of thestencil 16. One of the sides 3 of the cabinet 1 may be supplled, asshown in Figure 3, with an air outlet 75, disposed to the rear of theparti- ,tion 18.

Bearings 20 project inwardly from the sides 3 of the cabinet 1, as shownin Figure 1 and in the said bearings, shafts 21 are JOUI'Ilflled forrotation. The shafts 21 carry rollers 22 disposed to the rear of thestencil '16. About the rollers 22 is trained a. belt 23. The belt 23embodies a porous portion 24 and an im erforate portion 25. One of theshafts 21 is connected by a worm drive 26 or otherwise, with a shaft 27,forming part of a blower 28 mounted on the platform 11. The shaft 27 isconnected to an electric motor- 29, or other prime mover, mounted on theplatform 11 and located to the rear of the partition 18. If desired, theshaft 27 maybe connected operatively as at 33 with a changeableexhibitor 45, the display members of which may be caused to appearratthe lower pane -10.

In practical operation, a quantity of light material such as bran isdisposed in the hop-' per 12. The motor 29 drives the shaft 27 and theblower 28 is operated. An air blast is thus directed into the hopper 12and the bran is carried upwardly. Assuming that the porous portion 24 ofthe belt 23 lies behind the perforations 17 of the stencil 1-6,

the air, directed upwardly into the hopper- 12, will pass through (theporous upper portion of the hopper, through the perforations 17 of thestencil 16, through the porous portion 24 of the belt 23 and find anexit through the air outlet 75. The bran, carried upwardly by the airblast, will be deposited on the porous'portion of the hopper 12 in,

and simulates the appearance of a snowstorm, the bran collecting on theporous portion of the hopper, as shown at 80 and then settling downagain into the hopper,as

soon as the imperforete part 25 of the belt 23 arrives at theperforations '1'? of the stencil 16.

e What is claimed is 1. In a device of the class described a porousmember; a stencil cooperating there- .with;. means for directing a blastof air,

laden with finely divided material, against the porous member; and meansfor intermittently cutting oft the passage of ,air throu hthe stencil.

2. a device of the class porous member; a stencil cooperating therewith;means for directing a blast of air, laden with finely divided material,against the porous member; and a belt traversin the stencil, the beltembodying perforate and imperforate portions, the imperforate por tionof the-belt constituting means for cutting ed the passage of airthrough. the

stencil.

3. In a device of the class described, a porous hopper; finely dividedmaterial in I described j V intense air into the hopper with thehopper;an a means for intermittently directing the passage of air through thestencil.

d. In a device of the class described, a porous hopper; finely dividedmaterial in the hopper; means for directing an air'blast into the hoppera stencil cooperating with the.hopper;-and a belt mounted to traversethe stencil, the belt comprising perforate and imperforate portions, theimperforate portion of the belt constituting means for cuttingofi' thepassage of air through the stenci In testimon as my own, nature in thepresence of two witnesses.
